I have been playing with the UVM supplied by Gm in this vehicle and have some questions for anyone who has used the upfitters module.
First thing I see is it will not let me program it to sense rear door ajar? Says not supported and makes me remove it from the outputs before I can program the uvm.
The second thing. Wiring this thing up. I have two images to go with my explanation. I see its telling me I have to have switches to enable the output? Is there not a way to bypass this? We can not have switches. Need the conditions to automatically enable an output. For example - ignition on and keyfob detected needs to supply a power out. But my issue is its forcing me to add a switch on top of this? Also using the pin out below am I hooking the switch up to output enable 1, then the output comes out digital output 1? No where shows how this is supposed to actually be wired up.
For the switches its showing I must have resistors installed as well?
Any and all help with this would be great.
